Re: kqueue on OS X

Dear All,

I'm thinking of using kqueue on 10.3 in a single separate thread from the main, event loop thread. Is kqueue threadsafe?

So you're talking about your thread simultaneously making calls on a different kqueue with different file descriptors? Then I'm 95% sure the answer is yes; that's safe.

I don't know what happens if one thread tries to manipulate a kqueue the other is using or if one thread does IO operations on an FD while another thread is waiting for events on a kqueue in which that same FD is active. Without looking at the implementation, my intuition says those are bad ideas...

In sys/event.h there seems to two nonstandard kqueue filters, any documentation on how to make them work: EVFILT_MACHPORT and EVFILT_FS?

No idea here.

Cheers, Glen Low

Good luck.
